Question

2.The solution resulting from the addition of a nonvolatile solute to solvent will always have

-a higher freezing point than pure solvent

-a lower boiling point than pure solvent

-both a lower freezing point and a higher boiling point than pure solvent

-both a lower freezing point and lower boiling point than pure solvent

3. A solution of concentration 7.6% contains 7.6g of solute per liter of soultion

TRUE or FALSE

4. Hemolysis and crenation are "opposite" processes

TRUE or FALSE

5. Osmotic pressure is the amount of pressure needed to prevent the process of osmosis from occurring.

TRUE or FALSE

Answer 1

2)

There is elevation in boiling point and depression in freezing point

So,

boiling point always increases and freezing point always decreases when a nonvolatile solute is added to a solvent

Answer:

both a lower freezing point and a higher boiling point than pure solvent

3)

mass % = mass of solute * 100 / mass of solution

1 L of solution will not be 100 g

So,

this is false

Answer: false

4)

this is theoretical question which is true

Answer: True

5)

osmotic pressure is defined as pressure that needs to be applied to stop the osmosis process

Answer: True
